 * HI,
 * I would like to sue some JQuery functionality. I also had some JQuery plugins
   in use (JQuery Lazy Load, Slimbox2).
 * When adding my custom JS files, non-WP-plugin JQuery plugin files, and JQuery
   code files to my header, all is loaded properly (according to firebug).
 * BUT: e.g. the simple standard code
 * `$(document).ready(function($) ...`
 * throws a Firebug error stating that “$ is not a function”. When I do
 *     ```
       wp_deregister_script( 'jquery' );
       wp_enqueue_script( 'jquery', get_bloginfo('template_url')."/js/jquery-1.4.2.min.js", array());
       ```
   
 * all seems to work fine. But I am afraid I might break something like this…
 * My questions are:
 * 1. How to best reuse scripts from WP? I know the
 * `wp_enqueue_script( 'jquery_scrollto', "/js/jquery.scrollTo.js", array('jquery'));`
 * method, but even that did not work 100% and the error remained. Only when deregistering
   the standard jquery.js and re-regitering a custom jquery.1.4.2.js it worked. 
   Why?
    2. How to best queue scripts in the proper order? 3. When to place cusom
   script files that e.g. contain Jquery statements? 4. Is there a way to avoid 
   plugins adding already added code? E.g. the Jqery library? Lazy load added a 
   Google variant…
 * THANKS for any ideas and help. I would love to have some bright minds discuss
   with me that topic.
